Liver Function Tests

(SGPT, SGOT, Bilirubin (Direct/Indirect), Total Bilirubin, TPAG (Total Protein, Albumin, Globulin Ratio), GGTP.)

What

Liver function tests are blood tests used to help diagnose and monitor liver disease or damage. The tests measure the levels of certain enzymes and proteins in your blood.

Why

Liver function tests can be used to screen for liver infections, such as hepatitis, monitor the progression of a disease, such as viral or alcoholic hepatitis, and determine how well a treatment is working, measure the severity of a disease, particularly scarring of the liver (cirrhosis), and monitor possible side effects of medications.

Preparation

Your Physician will probably ask you to avoid eating food and taking some medications before your blood is drawn. The length of your fast and the medications you avoid depend on which liver function tests are being done.
